Repair of ceilings in housing society

Hello,

Yes, society can repair top foor ceiling. You can approach the co. op. registrar if society incure expenses of ground floor ceiling. 

Are you referring to Model Byelaws of Co-op. Housing Societies of Maharashtra? If so Byelaw 159 (a)(x) says Structural repairs of roofs of all flats. The roofs of all flats are made of RCC slabs. They can give way most usually, not necessarily due to corrosion of the steel reinforcements. The work you have reported is Society's responsibility. What the Society did is correct.

Kindly review my question am not talking of roof but ceiling of a premise on ground floor

In a multi-storey building the roof of the lower floor is its ceiling. These are only terminologies. I have also given the reason why it is the responsibility of the society. The structural stability of a modern multistorey building is based on the RCC structure. The responsibility to repair any part of a building is not necessarily based on it physical location. Please state what kind of repair was carried out. Was it just painting of the ceiling? Then it is the responsibility of the ground-floor tenant. If the plaster had given way or water was leaking through, it could have been due to any action by the upper floor tenant. If it could not be determined whether the upper floor or lower floor was responsible for the damage, then it could become the responsibility of the Society. A detailed account is necessary.
